Abstract
A calculator having an integration function has at least a key input section which in turn has registering keys for inputting data for setting a function to be integrated and an interval of integration, and executing keys for performing the definite integrating function. The function to be integrated is stored in a predetermined register of a RAM by key operation on the key input section. A dividing number for dividing the interval of integration input by the key operation is stored in another register. The interval of integration is divided by the dividing number stored in the latter register. The integrating function is performed sequentially based on the function to be integrated every interval of integration divided by a dividing means and the data input by the key operation for setting the interval of integration.
